Parallel Printers
Check printer manual to set up printer. If switches are changed it may be necessary to reset the
printer.
Check interconnecting cable to assure it is the proper cable.
Set the internal switches in the M-27 to agree with the printer. It is not necessary to reset the M-27
if switches are changed.
Connections to Printer
1. Make sure printer is set up to agree with M-27.
2. Connect printer cable to printer.
3. Turn on printer.
5. Connect printer cable to M-27. Cable goes toward top of M-27 with red strip in middle of
unit.
After data is accumulated, a printer is connected to the M-27 and the stored data is printed (see
Figure 9). The printer may be used while the M-27 is still gathering data to obtain intermediate results. No
data is lost in either unit until the unit is reset.
All the data may be printed, or only selected data if desired. It is possible to change the printout in
the middle to obtain, for instance, a 10-minute histogram for part of the time and a 1-minute histogram for
another.
The M-27 remembers previous PRINT keystrokes and will print only that data unless the
keystroke has been cleared.
Sample Printouts
Heading
A heading is printed when PRINT is pressed. It allows the user to write in identification data (see
Figure 10).
Summary
The summary data includes parameter data of how the M-27 is set up and a summary of all the M-
27 functions (see Figure 11).
Events
The event data is printed for events with data. It includes start time, run time, peak and max levels
as well as accumulated data for all three dosimeters (see Figure 12).
Histograms
Three separate histograms are computed as the data is accumulated with the appropriate exchange
rate and excluding data less than the threshold. Each minute an integrated average level is computed and
stored (see Figure 13).
For example, in the following histogram
